Description
Technical field
It the utility model is related to a kind of cylinder replacing device of four-roller stove volume reversable mill automatic thickness control device.
Background technology
The domestic most automatic thickness control devices for using four roll reversing rollers, wherein milling train of existing Heavy Plate Production line
（AGC）Adjusted for steel plate automatic thickness, be separately mounted to milling train fore side and driving side two sides, be milling train critical component.
In the operation of rolling, with the change of sotck thinkness, draught pressure and finished product thickness, pass through measuring cell and computer program control
System, micro correction is carried out to roller gap at any time.AGC oil cylinders adjust rolling mill roll through transmitting rolling loads of the milling train to slab
Distance, the thickness and template of steel plate are controlled, thereby may be ensured that thickness deviation control as defined in tolerance in scope.Simultaneously because
Using hydraulic AGC steel-fastening can be made to disengage rapidly, both save the time, it also avoid the damage such as scratch of the rolled piece to roll, burn.
But Medium and Heavy Plate Rolling belongs to high load capacity HI high impact production status, AGC cylinder seal parts are fragile, within causing
Leakage or oil cylinder are locally scratched, and coating comes off and catastrophic failure, and inevitable needs are changed.
Because equipment self-weight and related corollary equipment reach tens tons of weights, and traditional Replacement procedure is by manually pulling electricity
Dynamic cucurbit slings AGC oil cylinders, and slowly puts down AGC oil cylinders, and this Renewal process is time-consuming in traditional maintenance process
Arduously, and consume larger artificial and dangerous higher.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided one kind reduces labor intensity, while improves operation
The four-roller stove of efficiency and operational security rolls up the cylinder replacing device of reversable mill automatic thickness control device.
What the purpose of this utility model was realized in：
A kind of cylinder replacing device of four-roller stove volume reversable mill automatic thickness control device, the device is that a delivery is small
Car, carrier loader are located on the slideway above AGC oil cylinders, and four hydraulic cylinders, the work of four hydraulic cylinders are provided with carrier loader
A movable pulley is provided with stopper rod, the vehicle body of the carrier loader is provided with four fixed pulleys below movable pulley, together
Movable pulley in one vertical direction is with fixed pulley group into one group, and top is wound with steel wire rope, and one end of steel wire rope is fixed on delivery
On the vehicle body of dolly, the other end is hanging, and is cased with hanger in end.
The cylinder replacing device of the utility model four-roller stove volume reversable mill automatic thickness control device has advantages below：
The utility model dismounts AGC oil cylinders by special handling dolly, compared with traditional assembly and disassembly methods, this technique
Greatly reduce operation headcount and reduce labor intensity, while improve operating efficiency and operational security.
Brief description of the drawings
Fig. 1 is that the structure for the cylinder replacing device that the utility model four-roller stove rolls up reversable mill automatic thickness control device is shown
It is intended to.
In figure：Carrier loader 1, hydraulic cylinder 2, movable pulley 3, fixed pulley 4, steel wire rope 5, hanger 6.
Embodiment
Referring to Fig. 1, the cylinder replacing device of this four-roller stove volume reversable mill automatic thickness control device is a delivery
Dolly 1, carrier loader 1 are located on the slideway above AGC oil cylinders, and four hydraulic cylinders 2, four hydraulic pressure are provided with carrier loader 1
A movable pulley 3 is provided with the piston rod of cylinder 2, the vehicle body of the carrier loader 1 is provided with four in the lower section of movable pulley 3
Fixed pulley 4, the movable pulley 3 in same vertical direction form one group with fixed pulley 4, and top is wound with steel wire rope 5, steel wire rope 5
One end is fixed on the vehicle body of carrier loader 1, and the other end is hanging, and hanger 6 is cased with end, and the frock is in use, simultaneously
Start four hydraulic cylinders, the steel wire rope being attached thereto is transferred to AGC oil cylinders present position by assembly pulley, four hangers are hung
Put on the hangers of AGC oil cylinders, four hydraulic cylinders of reverse starting, will be sling at AGC oil cylinder slave unit base stations.
